Condo and Seasonal Home AC in South Florida: Approvals, Paperwork, Leaving and Coming Back

Who Decides What in a South Florida Condo

In a Florida condominium the association maintains the common elements, and the declaration can assign maintenance of limited common elements to the unit owner ^[7]. The statute never names air conditioners, so a condenser that serves one unit is the owner's job only if the declaration says so. The association also keeps a right to enter any unit to prevent damage ^[3].

Florida law defines the declaration of condominium as "the instrument or instruments by which a condominium is created" ^[6]. Limited common elements are common elements reserved for the use of a certain unit or units, "as specified in the declaration" ^[6]. Whether your condenser, air handler and line set are yours, the association's, or split between you is a line in that document, building by building.

The access right is the one owners rarely know. Florida law gives the association "the irrevocable right of access to each unit during reasonable hours" for maintenance and, in the statute's words, "as necessary to prevent damage to the common elements or to a unit" ^[3]. An AC drain overflowing into the unit below is that kind of damage.

Associations also check the contractor. Asked about condo associations, Frank Rey, Direct Cooling's owner, answered: "COI is needed. takes about 20-40 mins." A COI is the contractor's certificate of insurance. When an owner and a board read the declaration differently, Florida's Condominium Ombudsman describes itself as "a neutral resource" for owners, boards and associations ^[9].

Who signs, who approves and which office permits the address are covered step by step in the owner's side of a condo AC replacement. A board reviewing an owner's request can work from the nine questions a condo board should ask before approving an AC replacement, which puts license, permit, anchoring and drain protection on one page.

The Notice of Commencement Rule for an AC Replacement

A notice of commencement is a form the owner, or the owner's authorized agent, records in the county clerk's office before work starts on a property. Florida requires one for every improvement except those exempt under the $2,500 rule, so an AC replacement contract over $2,500 needs one ^{[1] [2]}. Only the owner may sign it, and recording it gives public notice that liens for the work may be recorded ^[1].

The confusion comes from a different section. Section 713.135 tells the permit office what to do when it issues a permit. One duty is collecting a copy of the recorded notice before the first inspection when the contract is over $5,000 ^[4]. Its last sentence reads: "This subsection does not apply to a direct contract to repair or replace an existing heating or air-conditioning system in an amount less than $15,000." ^[4] That sentence limits the permit office. It does not touch the owner's duty in section 713.13.

Three more rules in section 713.13 matter most to a condo owner who is away part of the year. The statute says: "The owner must sign the notice of commencement and no one else may be permitted to sign in his or her stead." ^[1] The statutory form gives the notary two boxes, physical presence or online notarization ^[1]. If you're out of state, ask your contractor early which one they'll use, because nobody can sign for you.

Timing is the second rule. If the improvement doesn't actually begin within 90 days after the notice is recorded, the notice is void ^[1]. Our view: record it close to the scheduled start, not when a quote is signed in spring for a fall installation.

The third rule is expiry. Unless the notice states another date, it expires 1 year after recording, and the statute says payments made by the owner after the expiration "are considered improper payments" ^[1]. A replacement that stalls for months while an owner is away can run into that line.

None of this is legal advice. This guide summarizes Florida statutes as published in 2026, and your declaration and your association's attorney control. The permit paperwork also changes at the county line between Palm Beach and Broward.

How Many Neighbors Are Also Away: Seasonal Homes by ZIP Code

In ZIP codes 33434, 33442 and 33484, the three most condo-dense of the nine ZIP codes we compared, 18.9 percent of homes (10,216 of 54,015) were held for seasonal, recreational or occasional use in the Census Bureau's 2020 to 2024 survey ^[5]. In the other six, the share was 8.6 percent (8,454 of 98,757), our arithmetic. Where half the homes are in large buildings, seasonal homes cluster.

Source: U.S. Census Bureau, American Community Survey 2020 to 2024 5-year estimates, tables B25001, B25004 and B25024, read through Census Reporter on November 2, 2026 ^[5]. The seasonal count is a survey estimate with a margin of error; in 33442 it is 4,885 plus or minus 675.

Across the nine ZIP codes, the share of seasonal homes rises with the share of homes in buildings of 10 or more units, a correlation of 0.77 by our arithmetic ^[5]. Nine places is a small set, and a correlation is not a cause. The practical reading is narrow: in a stacked building in these ZIP codes, the unit below yours and the one beside it are more likely than elsewhere to be empty in summer.

That matters for drain water. Florida's mechanical code requires backup protection for each cooling coil wherever an overflow could damage the building. One accepted option is a water-level device that "will shut off the equipment served in the event that the primary drain is blocked" ^[10]. The EPA's guidance is to dry water-damaged areas within 24 to 48 hours to prevent mold ^[11]. In a building where the neighbors are away, nobody may notice the water inside that window.

Asked about Century Village, Kings Point and Boca West, Frank named "pancake air handlers", the low, flat units mounted horizontally. With one of those, ask the contractor to show you where the backup protection sits and confirm it shuts the system off. Our page on AC repair in Kings Point lists its twelve condo sections by build year. Our page on AC repair in Century Village covers its 16 associations and how contractors get through the gates.

Before You Leave for the Season: Written Notice, Access and the Away Setting

Before a condo sits empty for months, give the association written notice that you are leaving and how to reach you. One of Florida's two tests presumes a unit abandoned when no tenant appears to have lived there for 2 consecutive months without prior written notice, and the association cannot reach the owner after reasonable inquiry. The board may then enter, turn on utilities and repair mold ^[3].

The abandoned-unit rule sits in section 718.111(5)(b). Once a unit is presumed abandoned, the board may inspect it, make repairs to the unit or the common elements serving it, repair it if mold or deterioration is present, and turn on the utilities ^[3]. Except in an emergency, it must first give 2 days' notice mailed or hand-delivered to the owner's address in the association's records, or sent electronically if the owner agreed to electronic notice ^[3].

The cost lands on the owner. Any expense the association incurs is chargeable to the unit owner and enforceable as an assessment under section 718.116 ^[3]. A written notice and a working phone number keep the board from ever reaching the presumption.

Four steps, in this order, cover the paperwork side of leaving:

1. Write to the association or its manager with your departure date, your return date and a phone number and email that reach you while you are away.
2. Name a local person who holds a key, and arrange the gate pass or contractor access your community uses.
3. Book an AC check before you go, so the drain is clear and the shut-off switch works.
4. Set the thermostat for an empty home and leave it running, not off.

The away setting is the one part people argue about. Asked whether to turn the AC off while you're gone, FPL says no. Its guidance for seasonal residents is to keep the AC set around 78 to 82 degrees when leaving for months ^[12]. Frank's experience points the same way from the other end. The mistake he sees most from seasonal residents is setting the thermostat too high, so the system runs too little and the drain backs up. What each away setting costs over a summer depends on the FPL rate and the home, and it is worth working out before you choose one.

A pre-departure AC maintenance visit is the time to have the drain line and pan cleared and that shut-off switch checked.

Coming Back, and When a Storm Passed While You Were Away

The Atlantic hurricane season runs from June 1 to November 30, peaks on September 10, and has most of its activity between mid-August and mid-October, according to the National Hurricane Center ^[8]. A May-to-October absence covers that whole peak. Coming back means checking two things before the thermostat: what the humidity did, and whether a storm reached the equipment.

The average season from 1991 to 2020 brought 14 named storms, 7 hurricanes and 3 major hurricanes ^[8]. A Boca Raton owner who leaves in May and returns in late October is away for the weeks that carry most of that activity. The decision that matters is made before you leave: who will look at the condenser and the air handler closet after a storm, and who calls a contractor if something is wrong.

The association has a role here too. Its right of access to a unit covers entry "as necessary to prevent damage to the common elements or to a unit" ^[3]. That is why the key and the phone number you left with the manager matter after a storm. If the system won't restart when you get back, call or text Direct Cooling at (561) 210-7605.

Indoors, read the humidity first. The EPA's guidance is to keep indoor humidity below 60 percent, ideally between 30 and 50 ^[11]. A reading above 60 percent in a closed unit tells you the away setting or the equipment did not keep up.

The order of checks on the day you return is in our AC start-up checklist for a seasonal home, which starts with a humidity reading and stops at the first sign of water. If the power went out or water reached the equipment while you were gone, read when it is safe to turn the AC back on after a hurricane before you touch the thermostat.

Managers have a separate job after the work: keeping the records a condo association should keep for every unit replacement.

Three Documents and One Phone Call

Most condo AC decisions in South Florida come back to three documents. The declaration says who owns and maintains the equipment. The notice of commencement, recorded for any replacement contract over $2,500 and signed by the owner, protects the job ^{[1] [2]}. Written notice to the association keeps an empty unit from being presumed abandoned after 2 months ^[3].

Our view: the notice of commencement deserves the most planning from a seasonal owner. The $15,000 figure gets repeated as the threshold, only the owner can sign, and the 90-day clock starts the day it is recorded. Ask your contractor who prepares the form and when it will be recorded, and plan the signature before you leave.
